Abstract
A method of manufacturing an optimized sheet metal () of a zirconium based alloy is described, which optimized sheet metal () defines a sheet plane (BA). The method comprises the steps of providing a sheet metal () of a zirconium based. alloy, subjecting the sheet metal () to at least a preparing cold rolling and a final cold rolling, wherein the preparing cold rolling and the final cold rolling are both performed in a common rolling direction, and heat treating the sheet metal () between the preparing cold rolling and the final cold rolling so that the zirconium based alloy is partially re-crystallized. A method of manufacturing a spacer grid using an optimized sheet metal () according to the invention is also described.
